You must be extremely young or new . Vosmug is the solo dev behind GHOST HUNTER VENA and XENOTAKE. everyone knows about these games and how incredibly good they are. there are thousands of people that have been waiting around 5 years for this new release to come out.
I'm 33 and run a server for the best nsfw game on the net. Nobody has ever mentioned these games nor did they pop up in any of my searches so far. Obviously this guy in't a big deal and neither are his games. I'm just giving some advice. Take it from someone who works in the industry you are out of your depth. just checked out his other games and yeah no not paying for something that looks like that without a demo. With graphics like that I dont know how those games are even supposed to get me hard.
"obviously this guy ain't a big deal"
I wouldn't be so dismissive about Vosmug, he may not rank as one of the biggest names in NSFW content but he has a strong enough rep for the consistent quality of the games he made. I played his 2 previous titles and have been following this one once in a while and after the first playthrough, shit I would've been fine giving him $10 for this one. Just because you never heard of him doesn't mean he doesn't mean his name carries no weight.
Your server is sorely lacking then.
Last time I checked there is a demo on both prior games (dlsite) and he has a WIP demo (which is long btw) for like the last year or two on his blog had you taken a moment to look. Checked out Naughty Nexus, clearly not enough members on there to justify your remarks, I wish you luck making it into the industry but you might need to gain a better attitude before you get anywhere.
